It's shaping up to be a very hot and smoky weekend on Mount Rainier.
With warm temperatures and light summit winds, expect it to feel very warm at all hours of the day and night. In fact, the National Weather Service has issued a Heat Advisory for today. Please plan ahead by packing extra water, electrolytes, and sun protection if you are traveling in the Park. The Muir Snowfield and upper mountain receive lots of direct sunlight and temperatures can soar as the day progresses.
If you are hiking to Camp Muir or are attempting a climb of the mountain this weekend, please start early, climb efficiently, and keep tabs on hydration and self-care. Travel in the late afternoon will be insufferable and may become dangerous for increased rockfall, crevasse fall, and dehydration. Heat related illnesses are largely preventable.
As of 8:30AM on Friday, Camp Muir and Ingraham Flats are full for tonight. There is limited availability for these areas tomorrow night. Get here early if you hope to climb the DC this weekend.
